Overview
The H8S/2329 Group and H8S/2328 Group are series of microcomputers (MCUs: microcomputer units), built around the H8S/2000 CPU, employing Renesas’ proprietary architecture, and equipped with supporting functions on-chip.

The H8S/2000 CPU has an internal 32-bit architecture, is provided with sixteen 16-bit general registers and a concise, optimized instruction set designed for high-speed operation, and can address a 16-Mbyte linear address space. The instruction set is upward-compatible with H8/300 and H8/300H CPU instructions at the object-code level, facilitating migration from the H8/300, H8/300L, or H8/300H Series.

On-chip supporting functions required for system configuration include DMA controller (DMAC)*1 and data transfer controller (DTC) bus masters, ROM and RAM, a 16-bit timer-pulse unit (TPU), programmable pulse generator (PPG), 8-bit timer, watchdog timer (WDT), serial communication interface (SCI), A/D converter, D/A converter, and I/O ports.

A high-functionality bus controller is also provided, enabling fast and easy connection of DRAM and other kinds of memory.

Single-power-supply flash memory (F-ZTAT™*2) and mask ROM versions are available, providing a quick and flexible response to conditions from ramp-up through full-scale volume production, even for applications with frequently changing specifications. ROM is connected to the CPU via a 16-bit data bus, enabling both byte and word data to be accessed in one state. Instruction fetching is thus speeded up, and processing speed increased.

The features of the H8S/2329 Group is shown in table 1.1.
